Abstract:
In this paper, we consider accelerated rendering
of high quality walkthrough animation sequences along
predefined paths.
To improve rendering performance we
use a combination of: a hybrid ray tracing and Image-Based
Rendering (IBR) technique, and
a novel perception-based antialiasing
technique. In our rendering solution we derive
as many pixels as possible using inexpensive IBR
techniques without affecting the animation quality.
A perception-based spatiotemporal
Animation Quality Metric (AQM) is used to automatically
guide such a hybrid rendering. The Image Flow (IF)
obtained as a by-product of the IBR computation
is an integral part of the AQM. The final animation
quality is enhanced by an efficient
spatiotemporal antialiasing, which utilizes
the IF to perform a motion-compensated filtering.
The filter parameters have been tuned using
the AQM predictions of animation quality as perceived
by the human observer. These parameters adapt locally to the visual
pattern velocity.
